Delivering in Hampstead
Hampstead is one of London's most protected conservation landscapes. Church Row, Downshire Hill, Well Walk and the Redington-Frognal conservation area all sit under strict Camden controls, and the ground behind most of these houses is unforgiving for basement work. We work here regularly, delivering full refurbishments and carefully engineered extensions that read as part of the original house, not tacked on.
Ushii is a London construction house working with private clients, family offices and developers across Hampstead and the surrounding prime postcodes. Every project is delivered by our own directly employed teams under a single point of accountability from first survey to final handover.

Answers
What Hampstead clients ask.

Do you handle Camden basement impact assessments?
Yes. We coordinate the BIA, structural engineering and party-wall process before ground breaks, so consents don't slow the programme.
What's a realistic Hampstead refurbishment programme?
A full four-storey Church Row refurbishment takes ten to fourteen months. Add three to six months for a new basement.
Do you work in the Redington-Frognal conservation area?
Regularly. Detailing and material palette are worked up with Camden conservation officers at concept stage so approvals move quickly.
Do I need planning permission for an extension in Hampstead?
Camden applies strict basement policy limiting depth and requiring a basement impact assessment, and slopes around the Heath make ground conditions a genuine engineering question. We confirm the position for your specific address before any design work begins, including whether the property sits inside a conservation area or carries an Article 4 direction.
Which council covers Hampstead?
Hampstead is covered by the London Borough of Camden. The Hampstead Conservation Area covers the village and the streets running down from the Heath, with a large number of listed houses within it.
How long does a project in Hampstead usually take?
Ten to sixteen months for a village house, longer if the basement is deep.
What kind of properties do you work on in Hampstead?
Georgian village houses, Victorian and Arts and Crafts villas, and apartments in converted houses. Our Hampstead work is mainly listed refurbishment, basement construction, roof and chimney restoration, and bespoke joinery.
Do you use subcontractors on Hampstead projects?
No. Every trade on site is directly employed by Ushii, so the people who price your Hampstead project are the people who build it.
